RING TRAVELER.

Application filed August 16, 1923. Serial No. @57,815.

To all whom it may concern:

Be it known that I, MICHAEL J. SHnnu-mm a citizen of the United States,residing at New Bedford, in the county of Bristol and State ofMassachusetts, have invented certain new and useful Improvements in RingTravelers; and I do hereby declare thefol lowing to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

The invention relates to, a novel form of ring traveler for spinning,and twisting machines and has for its object to provide a device of thecharacter indicated which will reduce the friction between the travelerand the ring to a minimum, which will maintain a uniform tension on thethread, and which will deliver the thread to the bobbin, tube or otherreceiving element without impairing the nap on the thread, the device asa whole constituting a strong durable construction, capable ofapplication to any of the standard types of spinning and twistingmachines.

The invention is, illustrated in the accompanying drawing, in which Fig.1 is an elevation of a single spindle of a spinning machine andits'associated ring, with the traveler applied thereto.

Fig. 2 is an enlarged elevation, the ring being shown in fragmentarysection.

Fig. 3 is an elevation at right angles to that shownin Fig. 2.

Referring tothe drawing, 1 indicates a spindle of an ordinary splnningmachine adapted to receive the usual bobbin or tube upon which thethread is laid up, as indicated at 2 Surrounding the spindle 1 is theusual ring 3, upon which the traveler, carrying the thread guide,rotates about the spindle.

The traveler comprises a body portion 10, generally elliptical in shape,having its lower side open, preferably made of flat spring steel, theends and upper mid section of the body portion being ground or machinedto form bearings for rollers 11, 11 and 12, the rollers 11 engaging theunder side of the top flange of the ring and the roller 12 engaging theupper face of the ring, as more particularly shown in Fig. 2. In orderto apply the roller 12 in position, it is preferably splitlongitudinally and the two halves are fitted over the bearing in the midsection of the body and secured Either formed as an integral part of, or

suitably connected to the body 10, is an arm13, preferably of springsteel, which extends upwardly from and over the body 10, terminating atits end in a loop oreye 14, in which is mounted a thimble or ferrule 15of wear resisting material, such as porcelain, bakelite or the like, thearm and the eye on the end thereof constituting the thread guide, fordirecting the thread onto the bobbin or tube, as the traveler movesaround the ring. v The particular advantage of employing a thimble ofthe character described in the eye of the thread guide, is the fact thatneither the thimble nor the thread is impaired during a normal operationof the machine, as'there is practically no wear on the interior of thethimble and the thread passes through the thimble in engagement with thesmooth surface thereof without suffering any abradi-ng action whichwould tend to rub the nan or loose fibre off the thread, whichis a verycommon and persistent objection to they use of thread guides in whichthe thread is brought directly in contact with a metallic surface.

In order to maintain a practically uniform tension on the thread, at alltimes, a helical spring 16 is interposed between the arm 13 and the body10, preferably in the manner shown in Fig, 2, one end of the springbeing connected to a small eye or arm 13 intermediate the length of thelatter and the opposite end of said spring being secured to an eye onthe body portion 10 of the traveler.

Experience has demonstrated that a traveler constructed and arranged asdescribed, is capable of use with various sized threads, so that it isnot necessary to supply a separate traveler for each particular size ofthread. It has also been demonstrated, by practical application, thatthe traveler requires much less force to carry it around the ring andthat the force required is pracis being laid up, and the properamount oftension may be accurately determined by the strength of the spring 16.

From the foregoing-description, it will be apparent that the traveler ishighly eflicient in operation, in that it practically eliminatesfriction in its operation, insures a substantially uniform tension onthe thread at all times, and completely avoids the. objectionableabrading ofthe thread, which tends to strip thenap therefrom.Furthermore, be-

- cause of thepeculiar structural form and arrangementof parts, thetraveler is exceptionally durable and, as it is substantially immunefrom all of thewearing effects of the ordinary type of traveler, it willoutlast the latter many times.

Also, within reasonable limits,':asingle traveler may be employed forvarious sized threads, thereby obviating thenecessity of applying adiffer ent traveler for each diflerent size of thread.

' A VVha-t I claim is;

- wardly from and over said body, said arm tension spring having aithread'guide'on its end, and a connected to said arm and body.

3. A travelerf for spinning and twisting machines comprising a bodyportion adaptedto engage a ring, an arm connected to one side of thebody and extending upwardly from and over the body, the said arm havinga thread 'guide'on its outer end, and a tensionspringconnectedto saidarm intermediate the length of the latter and to the opposite side ofthe body.

4. A traveler for spinning and twisting machines comprising a bodyportion adapted to engage a ring, an arm extending upwardly from saidbody, said arm having a thread guide including a loop on the end of thearm and a thimble of wear resisting material within said loop, and atension spring connected to said arm and body.

, 5. A traveler for spinning and twisting machines comprising a bodyportion adapted to engage a ring, an arm extending upwardly from saidbody, said arm having a thread guide including a loop on the end of thearm and a thimble of porcelain or the like within said loop, and atension spring connected to said arm and body.

6. A traveler for spinning and twisting machines which comprises a bodyportion substantially elliptical in form having one side open, rollersjournaled on the ends adjacent the open side and on the upper midsectionof the body and adapted to engage the lower and upper surfaces ofa ring, and an arm extending upwardly from said body said arm having athread guide on its outer end.

7. A traveler for spinning and twisting machines which comprises a bodyportion of flat spring metal bent to substantially elliptical form openon one side and having reduced bearing sections formed on the endsadjacent the open side and on the upper mid section, rollers journaledon said bearin sections adapted to engage the lower an upper surfaces ofa ring, and an arm extending upwardly from said body said arm having athread guide on its outer end.

In testimony whereof I afiix my signature.
